Establishing of digestibility coefficients of foodstuffs and nitrogen balance of mixtures with different levels and soures of protein
2008
Shindarska, Z. | Krasteva, M.
Balance experiments were carried out with 9 lambs (semifine-wool crosses for South-West Bulgaria) for determination of the digestibility coefficients of foodstuffs of whole ration mixtures containing 146 g, 171g and 190 g crude protein per kg dry matter, . It was obtained that the protein levels of the ration did not affect the dry and organic matter, the crude fibers, but affected the crude protein and crude fat digestibility. The different protein levels of the whole ration mixtures did not affect the nitrogen excreted by the faeces, but affected the nitrogen excreted by urine. The best retention of protein was by lambs fed with ration containing 171 g/dry matter crude protein , and the worst one at the highest quantity of crude protein.
